Rules for working with rewards​

Procedure for working with rewards:

  • Give the player a reward. Manually or through triggers.
  • Accept the reward. Automatically or manually, for example by clicking on the "receive" button.
  • Bonuses are automatically credited.
  • Save the player.

As we ensure consistency of data and changes in player variables, there is no need to stick to strict rules as when consuming purchases.

You can designate different types of rewards for yourself, for example: one-time and permanent.

Example of a one-time reward:

  • Login reward
  • Starter kit
  • Premium chest
  • Achievement reward

Such rewards can be accepted immediately or left for manual action by the player.

tip

Rewards are automatically credited upon acceptance. However, if you want to add non-standard changes to variables, you can make them by subscribing to the accepted event.

For example, you need to:

  • Add an item to the inventory
  • Change data in a JSON structure
  • Perform other manipulations not related to the player or not supported by the control panel.

Example of a permanent reward:

  • Unique sword / skin / car
  • VIP status / advertising off
  • DLC / levels / islands and other unlockable content

Permanent rewards do not need to be accepted. Once the reward has been given, it will always be visible to the user.

Rules for conducting a one-time reward with automatic acceptance​

Basic​

// 1. Give the reward
await gp.rewards.give({ tag: 'STARTER_PACK' });

// 2. The reward acceptance will be triggered automatically
// 3. The reward will be credited

// 4. Save the player on the server
await gp.player.sync();

With non-standard data changes​

Using adding health and mana potions to the inventory as an example:

// 1. Subscribe to the reward acceptance event
gp.rewards.on('accept', ({ reward }) => {
    switch (reward.tag) {
        case 'STARTER_PACK': {
            // 2. If necessary, add additional rewards
            inventory.push({ item: 'HP_POTION', amount: 100 });
            inventory.push({ item: 'MP_POTION', amount: 100 });

            gp.player.set('inventory', JSON.stringify(inventory));
            break;
        }
    }

    // 3. If necessary, update the UI to display variable changes
    myGame.refreshUI();
});

// 4. Give the reward
await gp.rewards.give({ tag: 'STARTER_PACK' });

// 5. The reward acceptance will be triggered automatically
// 6. The reward will be credited
// 7. The accept event will be called

// 8. Save the player on the server
await gp.player.sync();

Receiving rewards when starting the game​

Sometimes it may happen that the player did not have time to receive the rewards and save the progress, for example:

  • Closed / restarted the tab, browser or application
  • Turned off / broke the device
  • The game crashed.

They need to be received upon entering the game.

All unreceived rewards with automatic acceptance enabled are automatically accepted by the SDK at start-up.

info

Important. We don't know when the game is fully loaded and you're ready to process the accruals. Therefore, call the game start method gp.gameStart() when you are ready to receive rewards. After calling the game start, we will award the rewards, and you can subscribe to the reward acceptance event in advance.

If the reward does not have automatic acceptance, you can manually receive the rewards you need at game start:

// If manual reward processing is required,
// you must !! first !! subscribe to the accept event
gp.rewards.on('accept', ({ reward }) => {
    // Actions when receiving a reward
});

const rewardsToAcceptOnStartup = [
    'STARTER_PACK',
    'LEVEL_10',
    'LEVEL_20',
    //...
];

rewardsToAcceptOnStartup.forEach((rewardTag) => {
    const { reward, playerReward } = gp.reward.getReward(rewardTag);

    // Such a reward does not exist
    if (!reward) {
        return;
    }

    // Get the number of unreceived rewards
    const unacceptedRewardsLeft = playerReward.countTotal - playerReward.countAccepted;

    // Accept rewards
    for (let i = 0; i < unacceptedRewardsLeft; i++) {
        gp.reward.accept(reward.id);
    }
});

Rules for conducting a permanent reward​

// 1. Give the reward
await gp.rewards.give({ tag: 'NOOB_SKIN' });

// 2. Check for the presence of the reward at the right time
if (gp.rewards.has('NOOB_SKIN')) {
    // do something when you have the noob skin.
}

Actions​

Give reward​

+1 Request

To give a player a reward, you need to pass the ID or tag of the reward.

// By ID
gp.rewards.give({ id: 123 });
// By tag
gp.rewards.give({ tag: 'STARTER_PACK' });

You can give a reward with delayed saving. It will be saved together with the player's save.

FREE
gp.rewards.give({ id: 123, lazy: true });

The method returns the reward and player's reward:

const { reward, playerReward } = await gp.rewards.give({ id: 123 });

Accept reward​

FREE

After giving a reward, it can be accepted and variable changes credited.

// Accept by ID
gp.rewards.accept({ id: 123 });

// Accept by tag
gp.rewards.accept({ tag: 'STARTER_PACK' });

The method returns the reward and player's reward:

const { reward, playerReward } = await gp.rewards.accept({ id: 123 });

Properties​

List of rewards​

FREE

You have access to the entire list of rewards at once when the game starts. See reward fields.

gp.rewards.list.forEach((reward) => {
    // reward.id
    // reward.tag
    // reward.name
    // reward.description
    // reward.isAutoAccept
    // reward.mutations
});

List of given rewards​

FREE

You have access to the entire list of awarded rewards at once when the player is ready. See player's reward fields.

gp.rewards.givenList.forEach((playerReward) => {
    // playerReward.rewardId

    // playerReward.countAccepted
});

Getting information about a reward​

FREE

The method returns the reward and player's reward:

// By ID
const { reward, playerReward } = gp.rewards.getReward(123);

// The reward may not exist, make sure it does
if (reward) {
    console.info(reward.id, playerReward.countTotal);
}
